Types of Computer CPU Heatsinks

A computer CPU heatsink is a cooling device that helps to lower or stabilize the temperature levels of a computer's central processing unit (CPU). A CPU performs many computational operations, which can generate considerable heat. This can lead to hardware malfunctioning or even fires. Therefore, to cool down the CPU, engineers design computer heatsinks to draw the heat away from the CPU and dissipate it into the surrounding air. In the process, they also reduce the chances of the computer crashing.

Computer CPU heatsinks come in a variety of types depending on the design and material. They include the following;

• Active heatsink: An active heatsink is a type of computer CPU heatsink that is usually built with a fan or liquid cooling. It provides better CPU cooling for high-performance computers or systems. The active heatsink works by circulating the air and making it easier for the heat to be dissipated. As a result, it can prolong the lifespan of the computer. This helps users to achieve overclocking without worrying about the temperature levels.
• Passive heatsink: Passive heatsinks are solid metal ridges that are attached directly to the CPU without any fans, whatsoever. They rely on natural air convection to cool the CPU. The heatsink draws the heat away from the CPU and dissipates it into the surrounding air. Although passive heatsinks can cool the CPU, they only do so in computers with low power.
• Heat pipe heatsink: A heat pipe is a sealed hollow metal tube that removes heat away from the CPU. The inside of the pipe contains a specific fluid. When the CPU generates heat, the fluid inside gets vaporized. The vaporized fluid will then move to the outer edges of the pipe, where it will condense due to the cool temperatures. This successfully transfers the heat away from the CPU. Once the fluid cools down, it returns to the bottom of the heat pipe. Heat sinks with heat pipes can cool the CPU better than those without.
• Rugged fins: Computer CPU heatsinks with rugged fins have long, thin, and metal pieces that protrude at right angles and cover a larger surface area. As a result, they can cool the CPU more efficiently. The rugged fins are made from lightweight materials, making them easier to install and less expensive.

Features and functions of computer CPU heatsink

Features of CPU heatsink vary depending on design, functionality, and model, among others. Here are some common features and their functions:

• Fins

  They are the primary features of every heatsink. CPU heatsink fins have different shapes and sizes. They include round, flat, warped, and angled. Generally, fins increase surface area to facilitate better heat dissipation.

• Base

  The base of a CPU heatsink is usually solid and smooth to ensure good contact with the CPU surface. It comes in varying sizes depending on the heatsink model.

• Heat Pipes

  These tubes transfer heat from the CPU to the fins for dissipation. The pipes contain a special fluid that absorbs heat and moves towards the fins, where it evaporates. The heat pipes come in different diameters, depending on the amount of heat that needs to be transferred.

  Heatsink pipes can be straight, staggered, or nested. In straight heat pipes, all tubes are aligned in a straight fashion, making it easy for air to pass through. Staggered heat pipes have several tubes that are stacked but offset. The nesting design has smaller tubes inside larger ones.

  Heat pipes enhance heatsink performance by quickly moving heat away from the CPU. They also maximize efficiency and provide significant savings in space.

• Fan

  Many CPU heatsinks have a fan attached to it. The fan makes it an active CPU heatsink. The main role of the fan is to create airflow that moves the heat away from the fins. It also creates a convective current that improves overall heat dissipation. Depending on the design, the fan can be placed on top or at the bottom of the heatsink.

• Compatible mounting tools

  Every CPU heatsink comes with mounting tools to secure it on the CPU. The tools include screws, brackets, clips, and a backplate. In some models, the mounting tools double up as a retention system.

  The tools ensure the heatsink has consistent contact with the CPU. This prevents any possibility of the CPU and heatsink amusing resulting to inappropriately transferring heat.

Applications of the Computer CPU Heatsink

Every computer needs a reliable heatsink to manage and maintain safe operating temperatures for critical components to avoid overheating. Heatsinks effectively absorb and dissipate heat to keep systems running smoothly. Here's where the computer CPU heatsink is applied.

• Desktop Computers

  In standard desktop systems, the CPU and GPU are major heat sources. Central Processing Units (CPUs) and Graphics Processing Units (GPUs) work intensely during complex tasks, producing considerable heat. A proper computer CPU heatsink absorbs heat from the processor and releases it with airflow from the case fans, preventing overheating. It keeps all parts within safe temperature limits so desktops can work steadily without crashing or slowing down.

• Gaming Consoles

  Heatsinks are essential for high-performance gaming consoles. The CPUs and GPUs in these devices run at full capacity when processing demanding games, generating heat that can cause problems. Effective computer CPU heatsinks draw heat away from these processors and diffuse it into the air so that consoles can maintain stable temperatures during intense gaming sessions without risking overheating or lag.

• Servers

  Server farms contain many servers working hard around the clock to process and store data over the internet. Each server's CPU and other parts generate heat that must be managed. Heatsinks absorb heat and release it into the surrounding air to keep critical server components within safe temperature limits. This allows servers to maintain optimal performance levels while preventing overheating.

How to Choose CPU Heatsinks

The metal part of the heatsink and its baseplate both need to be sturdy and thick. A strong baseplate will not bend or warp during installation, so it will fit well on top of all the CPU cores. This helps the heatsink efficiently draw heat away from the chip. If a heatsink is poorly built, it can have air gaps between the CPU and baseplate. Air is a bad conductor of heat, and the CPU could overheat and become damaged. A well-made heatsink will last a long time without any problems.

Another important factor to consider when choosing computer CPU heatsinks is airflow direction. Most PC fans have an arrow printed on them to show which way the air blows. By placing the fan's airflow in the same direction as the heatsink's airflow, users can optimize air passage through the fins. Air will flow more easily, allowing the CPU to stay cooler.

Users also need to think about their PC case's size and cooling capacity. Bigger cases provide more space for higher-performing heatsinks and additional fans. However, smaller cases with limited airflow can benefit from more compact, efficient heatsinks. All computer parts should work well together.

When selecting CPU heatsinks, the following checklist should be kept in mind:

• The type and size of the CPU.
• The amount of heat the CPU generates.
• The CPU socket and compatibility requirements.
• The available space inside the PC case.
• The noise level of the fan.
• The budget.
• Other features, like RGB lighting or thermal paste included.
